Firefox: Winning the award for the most self-explanatory name, Netflix Playlist gives Netflix a feature it sorely needs: the ability to create custom, hand-picked episode playlists.

Normally, Netflix only allows you to play through episodes of a show in order. For dramas, that's perfect. For comedy or cartoon shows, it's safer to jump around a bit. This extension allows you to put all your favorite episodes into one continuous playlist. You can even use it to put together playlists of different shows. So, if you want to watch some Futurama then jump to Adventure Time without pausing, you can do that. The only downside is this extension is Firefox only. Note to any ambitious developers out there: a Chrome version of this would surely not go unappreciated.
